【Abstract】 Tea leaf-fertilizer is a kind of concentrated, multielement solution designed according to the nutrition state of tea orchard soil and nutritive absorption pattern of tea trees. It consists mainly of chelated microelement Mn, Zn, Cu, Mo and B, P, Mg while complemented with appropriate amount of K, N. It is the one which fit for tea leaf applying. Field experiments and datum analysis demonstrate that it can increase the tea yield by 20% while raising its quality and increasing its photosynthesis ability and elongating tenderness lasting time of the new tips distinctly.
